MATTRESS-FILLER-TREATING MACHINE.

Application filed March 21, 1927.

This invention relates broadly to fibre treating machines.

One of the objects of this invention is the provision of a novel form' of aeration tank for use in connection with fibre treating machines.

A still further object of this invention s the provision of an aeration tank which is adapted for cleaning cotton linters, kapok, felt fibres and the like for removing dust and seeds therefrom.

Another object of this invention is the provision of a closed circulation system associated with the aeration tank to provide a continuous path of movement for the material to be treated and means for delivering the material from the circuit without permitting the escape of dust from the aeration tank.

A still further object of this invention is the provision of a delivery nozzle which does not pass through the aeration tank and which is arranged adjacent the feed point of the device so that a single machine may be operated by one man froma given point.

These and many other objects such as the rapidity of treatment of the material, efficiency of cleaning thereof, rapidity of filling mattresses after the material has been cleaned and operation with little waste of raw material.

This invention resides in the construction, combination, arrangement and relative location of parts as will be more fully pointed out hereinafter.

Referring to the drawings,

The device of this invention is arranged for the treatment of cotton linters, down, kapok and similar fibres.

A grating is provided at the base of the aeration tank through which the seeds may fall when kapok-is being treated. A cover is provided for this grating to be placed thereover when other types of fibres are being treated. hen a circulation system is interruptedto permit delivery of the fibres to the mattress filling nozzle, a back pressure is created in the aeration tank which has a tendency to blow the dust therein into the surrounding atmosphere. The present form aeration tank has been modified so that this is prevented. All the parts to be controlled by an operator are arranged together so that they may. be supervised from a single point.

Referring to the drawings the aeration tank is shown comprising circular portions 1 and 3 connected by the tapering portion 2. Atapering portion 4 connects to the portion 1 and runs into the base portion 5. A removal pan 7 is provided in the base portion and has disposed above it and at an angle, the grating 6 upon which may be placed when desired, the cover member 6. A pipe or conduit 8 connects to the top of the aeration tank and at its bottom, is another conduit 9 which has a hopper or filling member 10 mounted thereon. The conduit 9 connects to the picker device 12 which is provided with a by-pass 17. From the picker device and the bypass a conduit 13 extends to the blower 14 which has a delivery pipe 15 which is connected to the pipe 8. The inlet of the picker device is provided with a gate 16 (Fig. 7) which, when in its upper position, closes off the by pass and when in its lower position, opens the by-pass and closes the inlet to the picker. A similar gate 18 is shown in the pipe 15 which closes off the pipe 8 when in its upper position, opening the pipe 15 to the nozzle 20. This gate is operated by means of the lever 21 which is connected to a foot lever 22. A spring 23 maintains the gate 18 in its lower position to cut off the nozzle but when the foot lever 22 is depressed, pipe 8 is closed and the nozzle 20 is opened to pipe 15. A smaller conduit 24 is connected to the inlet of a smaller blower 25 which has a dust bag 26 connected to its outlet. An open ended chamber 27 is mounted on the top of the member scription and small particles 3 and connects to the pipe 24. The chamber 27 is open to the atmosphere at 28. A ,screen or perforated member 11 is provided in the top of the aeration tank. In Figure 3 1t.will be noted that conduit 8 is connected to the aeration tank below the screen 11, While the pipe 24 connects to the tankand chamber 2 7 above the perforated member 11. The picker device is driven by means olishaft 29 through the agency of the motor 25'. The picker memberq30is mounted on a shaft 29 and a (cooperating member '31 is anounted .on another shaft 29. These two shafts aregeared together by means of the gears 32 and 33 of different sizes so that the picker members -operate at different speeds. The blower 14 is driven by means of the motor 14.

The method oi operation is as follows:

,Wheukapokis to betreatechthe grating 6 .is uncovered by removal'ot the plate 6 and the kapok raw material is placed into the hopper $10. The twoblowersare started in operation and thematerial ;is circulated through the pipe system andithe aeration tank; the valve 18 being in its lowermost normal position. Valve 16 is in its lowermost position so that the kapok materialdoes not pass through the picker which, isinot necessary i'orvthis typelof material; as the raw material circulates through this-system .it is broken .up and the :seeds fallithrough the grating 6 and any dust aredrawn through the screen 11 by meansol (dust bag 26. The mattress to be filled is placed over the nozzle 20 and the lever 22 is depressed whichdiverts the -:raw material :to

the nozzle20. Whenthe valve '18 closes thepipe 8, a back pressure is'created in the aerationtankwhich would normally force oreject dust into .the atmosphere but, 'dueito the arrangement ofthe chamber 27,-with its opening at a separated .point from ;the place where the conduit 24 conneetsto the aeration tank, the dust isdrawn throughthe pipe 2 l bcfore itican escape fromitheopening28.

lVhen other types of .raw material are treated, the plate 6 isplaoed-on the grating and gate 16 is .raised-soas'to closethe by-pass 17, :thus causing the raw material to pass :through the icker wherelit is brokenup and separated. therwise, the operation of the machine is substantially as described above. It will be apparent fromzthe foregoing dezthatwe have devised alnew and .:novel combination of elements for treating raw fibre stock.

It will be apparent to those'skilled .inithe art that many'changesin the detailsxot con- =municating with said .tank dust therefrom whenever a created in said system.

pressing .back

the blower 25 into the means a for connecting said struction and operation of the device will readily occur without departing from the spirit of our invention and we do not therefore desiresto be limited except as required by our appended claims.
